Filed: 1984-05-02
Abstract: PURPOSE:To encapsulate approximately least necessary amount of mercury in a fluorescent lamp with high accuracy by cooling the glass tube of fluorescent lamp in an evacuator and cohering mercury vapor to the locally cooled section then exhausting excessive mercury. CONSTITUTION:In the cooling process of glass tube 1, a portion of the glass tube 1 is locally cooled to 150 deg.C through a cooling nozzle 3 to produce the temperature difference higher than 100 deg.C against other portions and to drip mercury into the lamp. The dripped mercury will evaporate and cohere to the locally cooled section to produce a black stain 4. The encapsulated mercury except said stain 4 will become mercury vapor in short time because of high temperature of glass tube 1 then sucked through a vacuum pump and collected through a mercury adsorbing unit. Consequently, encapsulation of mercury can be controlled by adjusting the local cooling temperature, flow, time, etc.
